HARVEY, ILLINOIS, A CORPORATION OF ILLINOIS CARSTOI? Application filed Maya, 1931. Serial No.' 534,565. v

This invention pertains to railway car stops, its purpose being to provide a car stop that may be economically manufactured, readily installed by unskilled labor without the use of numerous or special tools, which occupies relatively small'traek space, which cushions the impact of the car, and which may be applied equally well to worn or new rails.

In accordance with this invention two stops are preferably employed, one being anchored to each rail. Each stop is also preferably constructed of a pair of shoes or plates adapted to engage the wheel of a car, the shoes being rigidly clamped to the bed or base of the rail,

being free of the head thereof and being so shaped as to cushion the impact by raising the wheel engaged prior to finally stopping the wheel.

A better understanding of this invention will be obtained from the following description given in connection with the drawing which illustrates one embodiment of the invention and in which:

Fig. l is a perspective of a carstop applied to one rail and illustrating the cushioning action,

Fig. 2 is a front elevation of one of the stops,

F ig. 3 is a partial section taken on the line 3 3 of Fig. 2, and y i Fig. tis a side elevation of a single stop illustrating the cushioning action by rais ing the Wheel.

It is preferable to use a pair of stops, one for each rail, each stop being the same, however, only` one is shown and only one will be described. Each stop comprises a pair of complementary shoes or plates l arranged o to be rigidly clamped together upon opposite sides of a rail 2.

' Thev shoes are preferably of cast malleable iron and are of the same configuration in reverse order, that is, they are complementary in order that they will fit upon opposite sides of the rail. The shoes are formed with an upper head or wheel engaging portion 3 having an inclined surface in the form of a curved forward edge 4 formed upon a radius equal to that of a standard car wheel when the stops are to berused against such wheels. The curved edge l is formed upon a center at a distance above the raily slightly in excess of the distance of the car wheel center fromzthe rail whereby when the car wheel strikesthe curved edge fl it `will ride upwardly a short distancebefore engaging` the entire surface and coming to a complete stop. This action will raise the wheel and car end and serve to cushion the impact of the wheel and more readily bring the car to a standstill without danger of damage to the running gear.

In order vthatthe shoes may be securely fastenedto the rails and to worn rails equally as well as to new rails, theshoes are clamped which they are designed. The lower portionv of the shoes are thickened and provided with aligned apertures to receive clamping bolts 7 which in cooperation with clamping boltsS draw the shoes together tightly against the bed of the rail. The shoes abovethe clamp.- ing groove are cut away as at 9 to provide clearance so that the shoes will not contact the head of the rail when in position, but will .be clamped to the base independently of the head. The upper ends of the shoes are also bored to receive a boltll by means of which the upper ends of the shoes may be secured together. Suitable distance Washers l2 may be inserted between the' .shoes tooproperly spacethe upper terminating ends of the two shoes. `To add strengthand greater rigidity to the stops, the shoes may be provided with vertical strengthening .ribs 13 along the clamping portions and a marginal flange 14 along the rear edge of the shoe. In order to transmit theforce of the impact to atie and thence to the ballast, the shoes are provided along the base thereof with a downwardly projecting abutment 16 whichiis arranged to engage the front vertical edge of a tie. -This abutment also causes the stop to serve as an anti-creep device in4 one direction. l f

It will be apparent from the above ,that

when a pair of complementary shoes are rigidly secured in position and clamped to the base of a rail repeated impacts will not aiiect the vertical position of the stop, that is, the stop will always remain in perfect alignment with the wheel. Furthern'iore, the worncondition `vof the head of the rail will have no elfect on the vertical position of the stop. It is apparent that no tools other than a wrench are necessary to apply the stop and that the stop may be applied by common rather than skilled labor, no drilling nor spacing of ties being required. It has been found that 'in actual installations the size of a stop may be such as to take up very little track space. In many installations vfor use in standard gauge rails the space occupied will be in the order of 16 inches.

It is .obvious that ymany changes may be made in the-details of construction from that embodiment illustrated lwithout departing from the spirit and scope of this invention asdefined in the claims appended hereto.

I claim:

l. A railway car stop comprising a shoe having awheel engaging head portion and means forclamping said head portion to the base ofa :track rail whereby the head is supported Afrom the base of the rail independent- 1y of the head of .the rail.

2. A railway car stop comprising a pair of complementary shoes arranged to lie upon opposite sides of a rail and terminating at one Aend in wheel engaging portions anc means for clamping said shoes to the base ofa track rail independently of the head of the rail.

.3. A railway car stop comprising a pair of complementary shoes adapted to lie upon opposte sides of a rail and terminating at one end in wheel engaging portions, said shoes being provided upon their other ends with `grooves each adapted to receivevopposite portions of the baseof a track rail independently -ofthe head of the rail7 and means for draw- -ing said shoes together to clamp opposite portions of the base of the rail rigidly therebetween.

4. yA railway car stop comprising a pair of complementary-shoes adapted to lie upon opposite sides of a rail and terminating at one end in wheel engaging portions, said shoes being provided upon their other ends with grooves each adapted to receive opposite flanges of the base of a track rail, and means for drawing said shoes together to clamp 'portions of the rail rigidly therebetween.

A railway car stop comprising a pair of complementary shoes adapted to lie upon opposite sides of a rail and terminating at vone end in wheel engaging portions, said shoes being provided upon their other ends with grooves each adapted to receive opposite flanges ofthe base of a track rail, and lmeans for drawing said shoes together to clamp portions of' the rail rigidly therebetween, said shoes being spaced from the head of the track rail when in position.

6. A railway car stop comprising a shoe having a wheel engaging head portion and means for clamping said head portion to the base of a track with the head portion above the ltrack in position to receive the impact of a car wheel, said head portion being arranged Yto raise the wheel to cushion the impact.
